COTTON-GIN.

To all whom it may concern:

- Be it known that I, WILLARD D. DQREMUS, a citizen of the UnitedStates, residing at 'Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Cotton-Grins, of whichthe following is a specification.

This invention relates to cotton gins.

Specification of Letters Patent.

DISTRICT OF COLUMBIA, ASSIGNO'R, BY IMPROVEMENT COMPANY, -A COR Theprincipal operative feature of a cotton gin constructed in accordancewith my invention is a series of saw cylinders, all adapted to revolvein the same direction,

Patented Oct. 26, 1909. Application filed December 20, 1907. Serial No.407,365.

and so placed in relation to each other that i the separation of thefiber and seed of seed cotton is performed by the coaction of thesurfaces of the cylinders. In the form of the machine shown in thepresent illustration a series of saw cylindersare mounted on a frame ofsuch form that the series extends substantially in a horizontal linefrom 'end to end. The seed cotton is fed to oneend of the series, thefiber is discharged from v the gin as it is separated from the seed bythe action of the various cylinders and the principal portion of theseed so separated is discharged from the machine at the end of theseries'opposite to that at which the seed cotton is introduced.

The saw cylinders employed, consist of a suitable number of gin saws 1mounted on shafts 2, the saws being so secured on the shafts in respectof each other as to leave between adjacent saws a space of a width toallow fiber to pass through it without injury and which is too narrowtopermit the entrance therein of cotton seed. The saw cylinders are somounted on a frame, the construction of which will be describedhereinafter, that the saws of each cylinder are opposite the centers ofthe space between the saws of the adjacent cylinder or of adjacentcylinders. Bearings?) in which the shafts of the saw cylinders aremounted are arranged at such distances apart that the teeth ofcontiguousv cylinders are maintained in close relation toeach other, thepreferred arrangement being that shown in the drawing wherein thetoothed peripheries of the saws of each cylinder overlap those of eachadjacent cylinder or cylinders. By this arrangement of theparts .thereis formed a continuous surface of saw teeth from end to end of the gin,and by reason of overlapping the saws ofadjacent cylinders as described,the transverse depression between the bodies of each pair of cylindersis of an angle too great to allow of the lodgment and injury over theoperative The distance which be varied if required to adapt the gin foruse on cotton containing seed of different size.- In practice I havefound that an overlap of such an extent as to give to the depressionsbetween the cylinders an approximately right angushown. Those cylinderslocated at the inlet or feed end of the gin are preferably provided withlarger teeth than those of the re maining cylinders in order to insureengagement of seed cotton in whatever condition it may be whenintroduced into "the machine. In the drawings I have shown the firstthree cylinders as havingthese larger teeth, but the number so made maybe varied as required. The seed cotton fed into the machine is firstengaged by the teeth of the ini-' tial cylinder and the teeth ofthis'cylinder will take a charge of fiber which, as the cylinderrevolves in the direction of the projection of its teeth, will becarried forward, bringing it into contact with the teeth of the secondcylinder. Inasmuch as all the cylinders revolve in the same directionthe seed cotton directly engaged by the teeth of the first cylinder andwith which such teeth are loaded will as it is drawn between the firstand second cylinders, be subjected to a combing action by means of whichthe seed of the cotton so engaged will be drawn from the fiber andcarried onward by the second cylinder. The cleaned fiber is carried tothe side of the cylinder opposite to that at which it is engaged andthere removed, The fiber directly engaged by the teeth of the firstcylinder will carry onward with it, by reason of frictional contact, aquantity of superimposed seed cotton, and this will be carried by theteeth of the second cylinder, a portion thereof being engaged and.ginned between thesecondand third cylinders while the seed removed bythe firstoperation together with excess seed cotton andthe seed removedby the second operation will be carried toward and operated upon in likemanner by succeeding cylinders in turn. The thickness of the charge ofseed cotton taken by the first cylinder is regulated by the adjustableplate 5, located atthe outlet side of the hopper 4, and by this only aquantity of seed cotton which may be operated upon to advantageispermitted vto pass into the gin. Each succeeding saw cylinder from theinlet end of the gun to the outlet end thereof is of a greater lengththan that of the preceding cylinder, the difference in length beingsufficient to furnish an overlap of at least one saw at each end. Bythis means the action of ginning is made certain in that it insuresrying forward of all' seed cotton not ginned,

. and seed, in order that the cotton may be presented to the action ofother cylinders following the series for action and the seed may bemoved onward and ultimately discharged fromthe gin.

The operation of the saw cylinders to free the cotton from seed 'and tomove onward excess of seed cotton and seed being performed by suchcylinders while revolving at a comparatively high rate of speed, it isnecessary to confine the material and to prevent ,its projection fromthe faces of the cylinders by centrifugal force. To accomplish this,side 'pieces 6 extend the entire length of the gin adjacent to the endsof the cylinders and their inner faces are of such a form as closely toinclose the cylinder ends and each cylinder is provided with a covering.The lower face of the covering conforms to the shape of the face of thecylinder over which it is placed and consists of two parts 7 and 8, bothof which are pivotally connected to and supported by the sidepieces 6.The sectional plates covering a number of the cylinders at the feed endofthe gin are formed to abut against 'each other in order to form acontinuouscovering and each part7, is provided with pivoted fingers 9,which'are adapted to bear against 1 flanges 10, with which the part 8 ofan adjacent covering is provided in order to retain the coverings inposition. Access to the cylinders is obtained by releasing the fingersfrom the flanges and by moving the 105 parts of the covering on theirpivots? The portion 8 of each coveringlha's on" the lower face thereof aprojection 11 by means of which cotton carried through the passageformed over thecylinders by theside pieces and the coverings is directedupon and closely confined-to the cylinder covered by it at a point ashort distance in advance of that at which the saws of the cylinder areintersected by those of the next succeeding cylinder in.115

order to insure the taking of a full charge by each tooth of the saws asit passes beneath the projection. The projection is preferably thin atits forward end where the cotton first contacts with it and graduallyincreases in thickness in order to form an inclined lower faceterminating close to the face of' the cylinder. The projection ispreferably of a construction or of such material as to render its faceyielding to avoid injury to the fiber of the cotton confined by it, andat the same time to offer no obstruction to the passage of cotton andseed. It may, with advantage,

be made of bristles of metal, hair, fiber or I similar material.

' the discharge end of the gin. In this form such as bolls,

heavier than seed cotton will be thrown character of matter of anythingat of covering which is particularly illustrated in Figs. 8 and 10.0fthe drawing, the portion 7 has extending from its upper face a flange12, which extendsacross it at an angle and which has an overlappingouter end 13. Portions 7 used in connection with the shorter sections 8each have a screw threaded rod 14:, which projects through a slot 15 inone of the side pieces 6 and on the rod is a thumb nut 16, adapted tobear against the outer face of the side piece in order to retain theportion 7 in any position to which it may be moved. v

The coverings of the construction last described are located at thatpart of the machine through'which will pass more or less seed entirelyfreed of fiber by the action of the first saw cylinders. As such seedbeing heavier than seed cotton or fiber is acted upon by the partially.uncove'redcylinders, it will be thrown from them at against theflange12 of the covering of the next cylinders and by it .will be deflectedfrom the machine. .Any foreign substances stones, dust, etc. being alsofrom the gin in like manner asthe free seed thus freeing the cotton fromobjectionable matter.

The plate adjustment 7 of the coverings is capable of to determine thequantity and thrown from the una cylinder which is allowed to pass fromthe in and therefore only clean seed and heavy foreign substances may bedischarged by this means and throwing out of fiber or of hering theretoin the manner described may be prevented. As the plate is movedupcovered portion of .ward on its pivot it forms an inclined surfaceby'which matter thrown as described and'by the position shown by full ofthe drawing the discharge the point at which it is located may beprevented.

The possibility of injury to fiber or of lodgment of seed betweencylinders during ginning as it takes place asdescribed, or of injury toexcess of seed cotton and seed carried along by the operation of thecylinders by subjecting retaining it in lines in Fig. 8

them to any grinding action between the sets of teeth of the cylindersis prevented by'giving to each cylinder after .the first, agreater/speed of rotation than that of the cylinder next in advance ofit and with whichit cooperates. Thus when fiber having tween the lasttwo cylinders.

To prevent the dischargefrom the machine of seed carryingfiber with clean seed, there is arranged a'djacent to the last cylinderof the series a board 17 capable of vertical adjustment andbescendingchute 18. that entirely clean seed will be thrown over its topfree of the machine while seed having a small quantity of fiber adheringto it will be dire'ctedin the chute 18. may reach the last cylinder withs'uificient board and the cylinder is a de- The board is so placed Anyseed which" desired number of saw cylinders may fiber on it to cause itto cling to the teeth of the last cylinder isvremoved in any suitableway as by the comb 19. This consists of a'bar 20, attached to the frameof the machine and having taper teeth extending upward therefrom. Theteeth correspond in thickness to the width of the space between-the sawsof the cylinder "and they are of a number to provide'a tooth to projectinto all the spaces between the saws and along the outer faces of theend saws. The comb is placed in such position'that the ends of the teethare located a short distance inside the rear face of the cylinder andfrom this point they extend downward intersecting the edges of the sawsin rear of the shaft on which the latter are mounted. As seed is carriedby the saws into contact with the teeth of the comb, it is and fallsinto the chute 18. leads to and communicates with the bottom of anupright cylindrical casing 21 into which it -discharges.- Arranged inthe casing is a worm 22 driven by suitable gearing 23, connected by abelt 2 with a band wheel on the shaft of one of the brushes which willbe hereinafter'described. Connected to the is capable of belng placedover and dischargfreed by the latter The'chute 18 ing into any desiredone of the openings over the saw cylinders. By this means any seedwhich, when it reaches the-last saw cylinder, has more or less fiber onit, is subjected for The sections are the second time to the ginningaction of any number of the cylinders which may be neces sary toentirely clean it.

For convenience of construction and to facilitate lengthening andshortening the frame of the machine to allow the use of a greater orless number of saw cylinders as may be required, the frame ispreferablymade up of sections. Each section is composed of a leg or standard 28,and an arm 29, extending therefrom. The arm of each standard preferablyextends therefrom at an angle and they are of such a form that the lowerface of the upper portion of one section rests upon the upper face ofthe lower portion of the arm of an adjoining section, there being atthese points overlapping flanges 30, which areconnected by bolts 31.

placed in pairs each member of which is placed on an opposite side ofthe gin to that of its fellow and the members are connected by a crosspiece 32, secured to opposite legs.

The saw cylinders are driven by any suitable gearing to impart to eachsuccessive cylinder from the inlet to the outlet of the machine, agreater speed than that of a preceding cylinder. This gearing may be ofany suitable arrangement such for instance as that shown particularly inFigs. 6 and 7, of the drawing. As shown the saw cylinders are arrangedin sets of three and each cylinder is provided on one end with a gearand the end of the outer cylinder of each set is provided at each endwith a gear. The first cylinder is provided with a gear 33, to which asuitable speed is imparted, the second cyl- 1nder is provided with agear 34, of somewhat smaller diameter than that of the first, whlle thethird cylinder has a gear 35, smaller in diameter than that of thesecond cylinder. The three gears all mesh with an intermediate gear 36,so that each successive cylinder rotates at a higher rate of speed thanthat of the one in advance of it. On the end of the thirdcylinder ofeach set opposite to that bearing the gear 35, is a gear 3 of the samediameter as that of the gear 33, and this gear 37 meshes with anintermediate gear 38. The intermediate gear 38, meshes with a gear 39,on the shaft of the first cylinder of the next set of cylinders and allthe gears of the second set of cylinders correspond in size to thoseemployed on the first set and are connected by an intermediate gear 40,corresponding to that of the first set. The first and last of eachcylinder of the following sets are connected as described throughout theseries and thus the desired relative speeds of the cylinders isobtained.

The brushes 41, by which the ginned fiber is removed from the ,saws aremounted in bearings 42, attached to the uprights of the frame. Thebearings are adjustable in order to allow the brushes to be moved towardthe cylinders to compensate for wear. The shaft of each brush isconcentric with'the shafts of the last two cylinders of one set ofcylinders and that of the shaft of the first cylinder of the next set,and is so placed as to contact with the lower faces of these threecylinders in order that in revolving it may free them from ginned fiber.In accordance with this arrangement the first section of the frameadjacent to the feed carries only two cylinders. Each brush is providedon its shaft with a band wheel 42, which is connected to and driven froma similar band wheel 43, fixed to the shaft of one of the in termediategears 38, by means of a belt 44. The relative sizes of the bandwheels issuch that the brushes are driven at a higher rate of speed than thecylinders The brushes are each partially surrounded by a casing-45,which communicates with a conduitr46, by which the fiber removedfromytlre sa'ws is conveyed to a condenser or place of storage. A numberof'these conduits are preferably employed, each having its inlet endarranged a different distance from the feed end of the gin in order toreceive and separately convey from the gin the fiber ginned by sawcylinders located at different distances from the inlet of seed cotton.In this way provision is made for separating and carrying to differentpoints of discharge the fiber'ginned at different points 1n the seriesofsaw cylinders. Thus should the fiber become at all shortened bycontact with a number of cylinders before being entlrely removed fromthe'seed, it will, when finally removed, be received by a separateconduit than that receiving the fiber operated upon by the firstcylinders only. Any suitable number of conduits may be employed and theyare arranged parallel to and communicate with each other throughopenings 47,,

arranged at various pointsiil'rtheir lengthin order thatfiber-receivedby' one if desired be introducedifintoand mixed W1 onduitma 3 that of another whichcbntains fiber of a similar length. Theopeningsiare provided.

with doors 48, rigidly mounted on rods 49, which are capable ofrotating. fEach rod 49 has on it a handle 50, locatedfon the outside ofthe conduit, and each handlejs provided with a dog 51, adapted to ent,ri ii'otches 1n a segment 52, in order that the doors may be moved toand held in position to open or close the openings. v

The brushes rotate in the direction indicated by the arrows in Fig. 4 ofthe drawing, and that side of the wall of the conduit of each brushagainst'which fiber will first be thrown after being removed from theteeth of the saw cylinders, is provided with a mote board 53, which maybe raised or lowered to permit discharging over it by the action of thebrush free of the fiber, any heavy foreign substances which may becarried by the fiber. The mote boards are held in ways 5 on the outerfaces of the conduits and they are moved to and retained in requiredposition byithe levers 55. The levers are pivoted to the frame of themachine to prevent the discharge of the fiber. Lo-

- my invention,

cated outside each conduit and below its mote board are the inclinedtroughs 59, which receive and discharge at the side of the gin thematter projected over the'mote board. I

In ginning cotton, by the means herein described, the fiber is at notime in its treatment subjected to injurious strain liable to shortenit. A charge of seed. cotton engaged by the teeth of the saws of acylinder is brought into position adjacent to the saws of'an adjoiningcylinder and the separation of the seed from the fiber is performed by Ithe combing action of the teeth of'this ad joining cylinder which latterrotates in the same direction at a higher rate of speedthan the firstcylinder. This method is obvia char e of seed cotton is engaged by theteeth of a rapidly revolving saw and brought j The fiber is freed fromforeign matter during ginning or upon being carried into a dischargeconduit rendering subsequent cleaning unnecessary. I

While I have herein described and claimed a specific construction ofapparatusfor carryin into effect the principle involved in I do not, ofcourse, in any sense limit myself thereto, as the invention residesbroadly in the idea of a series ofsaw cylinders soar-ranged that theteeth of adjacent cylinders coact to produce the effect described.-
